The difference between weathering and erosion is:
a. weathering causes a quick change in landforms and erosion causes a slow change in landforms.
b. weathering breaks rocks into sediments and erosion moves sediment from one place to another.
What is B?
100
Small pieces that break off of rocks.
What is sediments?
200
The chemical breakup of rocks caused by H+ and OH- ions in the water interacting with atoms in the rock.
What is hydrolysis?
200
When rainwater seeps into cracks in rocks and freezes, it expands and causes the rock to split apart.
The difference between erosion and deposition is:
a. erosion moves sediment from one place to another and deposition is a physical feature on the Earth.
b. deposition is the process of dropping , or depositing , sediment in a new location and erosion is the process of moving sediment from one place to another.
What is B?
200
Varying rates of weathering resulting from some rocks in an area being more resistant to weathering than others.
What is a differential weathering?
300
The process by which weathered rock is picked up and moved to a new place.
What is erosion?
300
If I have a rock which consists of 2 different minerals, one with a Mohs hardness of 9 and the other with a Mohs hardness of 2, which will weather slower?
What is the Mohs hardness of 9?
300
Erosion can change the shape of the land faster than a volcano can. True or False.
What is False?
300
Name a difference between mechanical and chemical weathering.
Chemical weathering changes the rocks and the atomic level (example answer others may be correct)
300
Decayed plant and animal remains (organic material) which provide nutrients to plants.
What is a humus?
400
Huge sheets of ice that move slowly over land.
What are glaciers?
400
Decomposers are most likely to be found here
What is the topsoil?
400
Water can weather rock by:
A. eroding soil
B. by freezing and melting
What is freezing and melting?
400
The difference between slump and a mudslide?
slumps occur when the base of the hill is saturated with water (example answer others may be correct)
400
The leaping or bouncing movement of sand or soil particles as they are transported in a fluid medium over an uneven surface.
What is saltation?
500
The sudden movement of rocks and soil down the side of a hill because of gravity and rain.
What is a landslide?
500
Plants like rye, alfalfa, or clover that are planted to hold and protect the soil?
What are cover crops?
500
Landslides are quick changes to the land. They can be caused by:
A. magma and rain
B. gravity and rain
What is gravity and rain?

The difference between topsoil and subsoil?
topsoil includes more organic material (other answers may be correct as well)
